Prevalent Distribution Of Conscious Processes On Either Side Of The Brain, Sohail Adnan, Mubasher Shah, Muhammad Fateen Rashed, Sadaf Nawab

Journal of Mind and Medical Sciences

Objectives. The brain has an intrinsic tendency for the lateralization of its functions. For instance, the left hemisphere assists in the comprehension and motor expression of language. What remains uncertain is whether conscious processes are also more prevalent in one hemisphere of the brain than the other. The epistemic goal of this research was to address this particular issue. Materials and Methods. We observed the rare pathological event of proximal occlusion of the middle cerebral artery (MCA), which halts blood flow to the central two-thirds of a hemisphere, and examined its effects on consciousness. We aggregated individual scores for eyes-opening …

Influence Of Core Temperature On Psychomotor Performance During Cold Weather Military Training, Douglas Jones, Rebecca Weller, Stephen Eggan, Nicholas Roberts, Weimin Zheng, Jay Heaney, Timothy Dunn

Journal of Human Performance in Extreme Environments

Purpose: Cold environments may deteriorate psychomotor performance due to slowing of neuronal signals, distractions caused by pain and discomfort, and a loss of manual dexterity. The extent to which core temperature (T_c) influences psychomotor performance in the cold has not been established. Therefore, psychomotor performance and T_c were assessed during a cold weather military training exercise to evaluate this relationship.

Methods: Thirty-six military personnel (age: 26 ± 4 yr, ht: 175 ± 8 cm, wt: 79.1 ± 11.1 kg) participating in cold weather training volunteered for this study. Participants completed a 10-min immersion in cold (1°C) water, …

Neuropeptide-S Affects Cognitive Impairment And Depression-Like Behavior On Mptpinduced Experimental Mouse Model Of Parkinson?S Disease, Ayşe Özkan, Mehmet Bülbül, Nari̇n Deri̇n, Osman Si̇nen, Güven Akçay, Hande Parlak, Mutay Aydin Aslan, Aysel Ağar

Turkish Journal of Medical Sciences

Background/aim: The present study proposes to investigate the effect of neuropeptide-S (NPS) on cognitive functions and depressionlike behavior of MPTP-induced experimental model of Parkinson's disease (PD). Materials and methods: Three-month-old C57BL/6 mice were randomly divided into three groups as; Control, Methyl-4-phenyl1,2,3,6-tetrahydropyridine (MPTP) and MPTP + NPS 0.1 nmol (received intraperitoneal injection of MPTP and intracerebroventricular injection of NPS, 0.1 nmol for seven days). The radial arm maze and pole tests were carried out, and the levels of tyrosine hydroxylase (TH) were determined using western blotting. A mass spectrometer was used to measure the levels of dopamine, glutamic acid, and glutamine. …

The Effects Of Long-Term Benzodiazepine Use And Withdrawal In The Elderly, Lydia Suchecki, Hannah Granger, Jamie Kellner, Mary Ellen Hethcox

Pharmacy and Wellness Review

Benzodiazepines remain a commonly prescribed medication in the United States, and the high usage of this drug class is especially a concern in the elderly population for several reasons. First, elderly patients metabolize drugs differently, leading to varying responses. Age-related changes also have a significant impact on the effects of benzodiazepines. Second, elderly patients are more likely to be taking multiple centrally-acting drugs, which can further exacerbate negative effects. In regard to long-term benzodiazepine use, elderly patients experience an increased risk of cognitive impairment, motor vehicle accidents, decline in physical performance, falls and subsequent fractures, and sleep disturbances. Withdrawal is …

Cognitive Problems Related To Vertebro-Basilar Circulation, Abdulkadi̇r Koçer

Turkish Journal of Medical Sciences

Neurodegenerative disorders are characterized by decreased regional cerebral blood flow. Supporting this concept, both cognitive training exercises and physical activity promote blood flow increase and correlate with healthy cognitive aging. The terminal branches of the posterior circulation supply blood to areas of the brain, such as the thalamus, hippocampus, occipital lobe, and cerebellum, involved with important intellectual functions, particularly recent memory, visual-spatial functioning, and visuomotor adaptations. Amnesia and visual agnosia may be a complication of not only posterior circulation infarctions but also vertebrobasilar insufficiency (VBI) without accompanying structural infarcts. The cognitive impairment may be a manifestation of transient attacks and …

The Impact Of Attention Training On Children With Low Vision: A Randomized Trial, Bi̇lge Başakci Çalik, Ali̇ Ki̇ti̇ş, Uğur Cavlak, Atti̇la Oğuzhanoğlu

Turkish Journal of Medical Sciences

The purpose of this study was to show the effectiveness of a 6-week attention training program on the cognition, quality of life (QOL), and activities of daily living in children with low vision. Materials and methods: Included in this study were 20 children with low vision, aged 7-12 years. The children were divided into 2 groups. While the first group (n = 10) participated in a 6-week Pay Attention© training program 3 times a week for 30 min, the second group (n = 10) was the control. Before and after the program, all of the participants were evaluated using a …
